DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way ofexample, with reference to the accompanying drawings.

A first exemplary system, which embodies the present invention, will nowbe described.

Referring to FIG. 1, the first exemplary system comprises a mobile phone2 and a server 3.

The mobile phone 2 can communicate with the server 3 via a mobile phonenetwork 4 and the Internet 5 using XML messages and the HTTP protocol.The mobile phone 2 supports J2ME (Java 2 Micro Edition) MIDlets and thefitness program functions of the mobile phone 2 are implemented by aMIDlet.

The server 3 is a conventional HTTP server such as Apache.

Referring to FIG. 2, the mobile phone 2 comprises an antenna 21, an rfsubsystem 22, a baseband DSP (digital signal processing) subsystem 23,an analog audio subsystem 24, a loudspeaker 25, a microphone 26, acontroller 27, a liquid crystal display 28, a keypad 29, memory 30, abattery 31, a power supply circuit 32 and a SIM (subscriber identitymodule) 33 and an infrared transceiver 34.

The rf subsystem 22 contains the if and rf circuits of the mobilephone's transmitter and receiver and a frequency synthesizer for tuningthe mobile phone's transmitter and receiver. The antenna 21 is coupledto the rf subsystem 22 for the reception and transmission of radiowaves.

The baseband DSP subsystem 23 is coupled to the rf subsystem 22 toreceive baseband signals therefrom and for sending baseband modulationsignals thereto. The baseband DSP subsystems 23 includes codec functionswhich are well-known in the art.

The analog audio subsystem 24 is coupled to the baseband DSP subsystem23 and receives demodulated audio therefrom. The analog audio subsystem24 amplifies the demodulated audio and applies it to the loudspeaker 25.Acoustic signals, detected by the microphone 26, are pre-amplified bythe analog audio subsystem 24 and sent to the baseband DSP subsystem 24for coding.

The controller 27 controls the operation of the mobile phone 2. To thisend, it is coupled to the rf subsystem 22 for supplying tuninginstructions to the frequency synthesizer and to the baseband DSPsubsystem for supplying control data and management data fortransmission. The controller 27 operates according to a program storedin the memory 30 with reference to the contents of the SIM 33. Thememory 30 is shown separately from the controller 27. However, it may beintegrated with the controller 27.

The display device 28 is connected to the controller 27 for receivingcontrol data and the keypad 29 is connected to the controller 27 forsupplying user input data signals thereto.

The battery 31 is connected to the power supply circuit 32 whichprovides regulated power at the various voltages used by the componentsof the mobile phone. The positive terminal of the battery 31 isconnected to an analog-to-digital converter (ADC) input of thecontroller 27.

Among the programs stored in the memory 30 is a Java virtual machineprogram that supports J2ME (Java 2 Micro Edition) MIDP (MobileInformation Device Profile) 2.0 programming of the mobile phone 2 and afitness trainer MIDlet 35. The fitness trainer MIDlet 35 can generate anexercise program for a user, guide the user through the exercise programand adjust the program on the basis of the user's progress through anexercise program.

The fitness trainer MIDlet 35 will now be described in detail.

Referring to FIG. 3, when the user instructs the mobile phone 2 toexecute the fitness trainer MIDlet, the MIDlet 35 is instantiated.During the instantiation of the MIDlet, the MIDlet 35 displays a screen101 inviting the user to agree to the terms of usage of the MIDlet. Ifthe user declines to accept the conditions by selecting a Declinecommand, a confirmatory screen 102 is displayed and the MIDlet 35terminates. If the user accepts the terms by selecting an Agree command,the MIDlet 35 displays a confirmatory screen 103 and then attempts toread configuration data from a record store. If a record store seems tobe present but contains corrupted data, the MIDlet 35 determines whetherthe record store memory is so corrupted that it is not even possible toidentify the regions that relate to the MIDlet. In the case of severecorruption of the record store memory, the MIDlet 35 generates an errormessage screen 104 and destroys itself. If, on the other hand, theMIDlet's record store is identifiable but contains meaningless data, theMIDlet 35 clears the record store and the MIDlet 35 enters a set upprocess 137 (FIG. 10).

Similarly, if there is no record store, as would be the case when theMIDlet 35 is first executed on the mobile phone 2, or there is an emptyrecord store, the MIDlet 35 enters the set up process 137.

Referring to FIG. 4, when the MIDlet 35 enters the set up process, theMIDlet 35 displays an invitation screen 105 inviting the user to entertheir detail for a short period. The user is then presented with a listscreen 106 which enables the user to enter their gender. When the userhas entered their gender by selecting the appropriate option in the listscreen 106, the selection is confirmed in a gender confirmation screen107.

The gender confirmation screen 107 is displayed for short period and isthen replaced by an age input screen 108. When the user has input theirage, an age confirmation screen 109 is displayed for a short period.

The age confirmation screen 109 is replaced by a measurement units listscreen 110 which enables the user to select one of the metric, Imperialavoirdupois and US avoirdupois systems for display and input of lengthsand weights. When the user has selected a system of units, a unitsconfirmation screen 111 is displayed for a short period.

After the selected units have been confirmed, the user is presented witha height input screen 112. The height input screen 112 invites the userto input their height in units of the selected system of units, i.e.centimetres for metric and feet and inches for both avoirdupois systems.The input height is confirmed by a height confirmation screen 113 whichis displayed for a short period.

After the input height has been confirmed, the user is presented with aweight input screen 114. The weight input screen 114 invites the user toinput their weight in units of the selected system of units, i.e.kilograms for metric, stones and pounds for Imperial avoirdupois andpounds for US avoirdupois. The input weight is confirmed by a weightconfirmation screen 115 which is displayed for a short period.

Non-metric height and weight values are converted into metric values forstorage by the MIDlet 35. All calculations use the metric values, thenon-metric values only being used for user interface purposes.

After the input weight has been confirmed, the user is presented with anendurance list screen 116 which enables the user to input their level ofendurance (high, moderate and low). The user may obtain assistance inselecting the correct level by selecting a Help command from a menurevealed by selecting the options. Once the user has selected theirendurance level, an endurance confirmation screen 117 is displayed for ashort period.

After the input endurance has been confirmed, the user is presented witha strength list screen 118 which enables the user to input their levelof strength (high, moderate and low). The user may obtain assistance inselecting the correct level by selecting a help option from the optionsmenu. Once the user has selected their strength level, an enduranceconfirmation screen 119 is displayed for a short period.

The entered personal details are now saved to the MIDlet's record storeand the settings process 137 is exited as this is the first time that ithas been entered.

Referring to FIG. 10, when the MIDlet 35 has been loaded successfully,the user is presented with a main screen 132 which comprises a list ofoptions consisting of Fast Start, Planner, Start Planned, Diary,Settings, Instructions and Synchronization.

If the user selects the Settings option, the MIDlet 35 clears the user'ssettings and performs the setting process 137.

Referring again to FIG. 4, the user is initially presented with asettings list screen 120, containing Personal Data, Additional Data,Change Password and Reset Data options, is displayed.

If the user selects the Personal Data option, a password entry screen121 is displayed. The user must input a password, if it has beenpreviously set, using the password entry screen 121. If the password iscorrect, the invitation screen 105 is shown and the user can proceedthrough screens 105 to 119 as described above. However, after screen119, the user is returned to the settings list screen 120. If thepassword is not correctly entered, a password error screen 122 isdisplayed for a short period and the user is the presented with thepassword entry screen 121 again.

A default resting heat rate is determined on the basis of the user'sendurance level. Referring to FIG. 5, the entered endurance level isidentified (step s1) and if the entered endurance level is LOW, theresting heart rate is set to 70 beats per minute (bpm) (step s2). If theentered endurance level is MODERATE, the resting heart rate is set to 50bpm (step s3) and, if the entered endurance level is HIGH, the restingheart rate is set to 45 bpm (step s4).

A default maximum heart rate is determined by the MIDlet 35 on the basisof the user's entered age. Referring to FIG. 6, the default maximumheart rate is calculated (step s11) according to Equation 1:

maximum heart rate=208−(0.7×age)  (1)

where age is the user's age entered by the user in years.

Referring to FIG. 7, if the user selects the Additional Data option fromthe settings list screen 120, the user is presented with heart rate editscreen 123. The heart rate edit screen 123 includes two textfieldelements which enable the user to enter their maximum and resting heartrates respectively. If the user has not previously entered heart rates,the textfields contain the default values whose determination isdescribed above. If the either of the values is changed by the user, thenew value is written to the record store. The user can return to thesettings list screen 120 by selecting the Back command.

Referring to FIG. 8, if the user selects the Change Password option fromthe settings list screen 120, it is determined whether a password hasbeen previously entered. If a password has not been set previously, theuser is presented with an enter new password screen 124. When the userhas selected the OK command of the new password screen 124, it isdetermined whether the text property of the new password textfield 124 ais an empty string. If the text property of the new password textfield124 a is an empty string, a password disabled screen 125 is displayedfor a short period and the MIDlet 35 displays the settings list screen120 again.

If, however, the text property of the new password textfield 124 a isnot an empty string, the user is presented with a confirm passwordscreen 126. The user must correctly enter their new password at thispoint. If their new password is not correctly entered, a passwordincorrect screen 127 is displayed for a short period before the passwordentry screen 126 is displayed again. However, if the password iscorrectly re-entered, a password changed screen 128 is displayed for ashort period and the MIDlet 35 then redisplays the settings list screen120.

If, after selection of Change Password option, it is determined that apassword has already been set, the user is presented with a passwordentry screen 129. If the user incorrectly enters their password into thepassword entry screen 129, the password incorrect screen 127 isdisplayed for a short period after which the password entry screen 129is redisplayed. If, however, the user enters their password correctly,the enter new password screen 124 is displayed and the user can set upthe new password as described above.

Referring to FIG. 9, if the user selects the Reset data option from thesettings list screen 120, a reset confirmation screen 130 is displayedso that the user can confirm that resetting is desired or abort theresetting. If the user confirms that resetting is desired, the userdata, including the password, is cleared and a confirmation screen 131is displayed for a short period. While the confirmation screen is beingdisplayed, the record store is updated.

If, when the MIDlet 35 is instantiated, a valid set of configurationdata is successfully read from the record store, the MIDlet 35 is readyfor use.

If the user selects the Fast Start option from the main screen, theMIDlet 35 performs a process 133 to guide the user through anindependent exercise session 133 which is appropriate for the user.

After the selection of the Fast Start option, the user is presented withan exercise type list screen 140 comprising Fitness Center, Outdoor andSwimming options.

Referring to FIG. 11, if the user selects the Fitness Center option, theuser is presented with a session duration list screen 141 which enablesthe user to select 30, 45, 60 or 90 minutes for the duration of theexercise session. When the user has selected a session duration, theselected duration is displayed for a short period in a session durationconfirmation screen 142. The session duration screen 142 is replaced bya discipline selection multiselect list screen 143. The disciplineselection multiselect list screen 143 comprises a list of disciplinesthat are typically available in a fitness center and, in the presentexample, comprise Cycling, Running, Rowing and Stepping. The user canselect one or more of the listed disciplines.

After selecting one or more disciplines, the user is presented with atrainer selection list screen 144 which enables the user to selectbetween hard and easy virtual trainers.

Once the trainer has been selected, the user is presented with adiscipline list screen 145 which consists of the selected activities.The user can now select the first discipline to be performed. In thepresent example, the user has selected the cycling and runningdisciplines and chooses to do the cycling first. If the user hasselected only one discipline, screen 145 is skipped. Icons beside theelements in the discipline list screen 145 indicate whether thedisciplines have not been started, been completed or been interrupted.

If the easy trainer has been selected, the activities to be performed ineach discipline are selected randomly from the a, b and c sections ofTable 8 below for low, moderate and high endurance users respectively.However, if the hard trainer has been selected, the activities to beperformed in each discipline are selected randomly from the b, c and dsections of Table 8 below for low, moderate and high endurance usersrespectively. If a plurality of disciplines has been selected, theactivities are selected so as to tend to divide the session durationevenly between the disciplines. It is not essential that either aperfectly even distribution or an exact match to the selected sessionduration be achieved.

On selecting the starting discipline, the user is presented for a shortperiod with an information screen 146 which reminds the user to warm upbefore exercising. The information screen 146 is replaced by a exerciseguidance screen 147.

Referring to FIG. 12, the exercise guidance screen 147 comprises a title1001, a timer section 1002, an intensity indicator 1003 and aninstruction 1004. The title 1001 states the discipline and the durationof the activity. The timer section 1002 comprises a circular graphicwith sections that are sequentially lightened to indicate the passage oftime. The intensity indicator 1003 comprises four sections 1003 a, 1003b, 1003 c, 1003 d corresponding to respectively to intensity levels a,b, c and d. The section 1003 b corresponding current intensity indicatesa heart rate target range commensurate with the current intensity. Theother section 1003 a, 1003 c and 1003 d merely state the correspondingintensity level. The intensity level is based on the users personal dataand additional data, if any. The instruction 1004 may informs the userof a narrower target heart rate within the range corresponding to thecurrent intensity level or that they must change speed, stop or restartwhen a beep is sounded.

The target heart rate is calculated from the user's personal andadditional data.

When the user selects the Start command (not shown) from the exerciseguidance screen 147, the MIDlet 35 begins timing the user's performanceof the selected discipline. During this period, the MIDlet 35occasionally displays motivational messages in motivational messagescreens 148. For instance, a motivational message may inform a user of afoodstuff that has a calorific value corresponding to the amount ofenergy notionally produced by the user while performing the discipline.The motivational message screens 148 are displayed for short periodsbefore the display reverts to the exercise guidance screen 147.

If the user selects the Options from the exercise guidance screen 147,the user is presented with an options menu 149 comprising End disciplineand Exit session options. If the user selects the End discipline option,the user is presented with an end discipline confirmation screen 150and, if the user confirms that the discipline is to be ended, the MIDlet35 stops timing and displays the discipline list screen 145 again, ifmore than one discipline was selected and at least one has not beenattempted, otherwise the exercise type list screen 140 is displayedagain.

If the user selects the Exit session option, the user is presented withan exit session confirmation screen 151 and, if the user confirms thatthe discipline is to be ended, the MIDlet 35 stops timing and displaysthe exercise type list screen 140 again.

If the user selects the Pause command from the exercise guidance screen147, the user is presented with a pause confirmation screen 152. If theuser confirms that the current discipline is to be paused, a pauseddiscipline screen 153 is displayed. The paused discipline screen 153 isthe exercise guidance screen 147 with the area 1002 a bearing the timecolored red and the time flashing, and the Pause command replaced with aContinue command. The MIDlet's timing of the discipline is paused whilethe paused discipline screen 153 is being displayed. When the userselects the Continue command from the paused discipline screen 153, theMIDlet 35 restarts its timing operation and displays the exerciseguidance screen 147 again. The user can also end the current disciplineor exit the current session by selecting Options from the pauseddiscipline screen 153 which takes the user to the options menu 149.

When the period set for the current discipline has elapsed, allowing forany pauses, the MIDlet 35 displays a discipline completed screen 154.The MIDlet 35 also produces an audible indication that the set periodhas elapsed. When the user acknowledges the ending of the discipline byselecting the Done command of the discipline completed screen 154, aregistration list screen 155 is displayed.

The registration list screen 155 lists different options for registeringthe completed discipline. The options comprise Work load in Watts,kcalories, average HR and How was it? (Hidden in FIG. 11 but can bescrolled down to). The first three options require the user to haveaccess to suitable measuring devices. These may be standalone devices ordevices integrated into exercise apparatuses. The fourth option enablesa user to provide feedback in the absence of suitable measuring devices.

If the user selects Work load in Watts, the user is presented with awork load entry screen 156 which enables the user to enter the averagepower produced during performance of the selected discipline. When theaverage power has been input, the user is presented with a confirmationscreen 157 for a short period.

If the user selects kcalories, the user is presented with a kilocaloriesentry screen 158 which enables the user to enter the energy used duringperformance of the selected discipline. When the energy used has beeninput, the user is presented with a confirmation screen 159 for a shortperiod.

If the user selects Average HR, the user is presented with an averageheart rate entry screen 160 which enables the user to enter theiraverage heart rate during performance of the selected discipline. Whenthe user's average heart rate has been input, the user is presented witha confirmation screen 161 for a short period.

If the user selects How was it?, the user is presented with anexperienced intensity list screen 162 which enables the user to select alevel of intensity corresponding to their experience of the performanceof the selected discipline. Help in making the selection can be obtainedby selecting Options from the experienced intensity list screen 162.When the user has selected the appropriate intensity, the user ispresented with a confirmation screen 163 for a short period.

The MIDlet 35 now calculates a number of points which represent thevalue of the performance of the selected discipline in arbitrary units.The calculation of the points will be described below.

The points earned is displayed for a short period in a completionmessage screen 164. Then, if there remain uncompleted disciplines in thecurrent session, a rest information screen 165 is displayed. The usercan select a Next command from the rest information screen 165 whichreturns the user to the discipline list screen 145.

If all disciplines in the current session have been completed, thecompletion message screen 164 is followed by a points summary screen 166which displays the points earned in the current session and the totalpoints earned. The points summary screen 166 provides the user with Doneand Send commands. Selecting the Done command cause a done confirmationscreen 167 to be displayed. If the user confirms that the session shouldend, the MIDlet 35 displays the main screen 132.

If the user selects the Send command, the MIDlet 35 send a summary ofthe session to a remote server by SMS. On completion of thetransmission, the user is presented with a transmission confirmationscreen 169 for a short period after which the main screen 132 isdisplayed.

Referring to FIG. 13, if the user selects the Outdoor option from theexercise type list screen 140, the user is presented with an outdoordiscipline list screen 170. The user is able to select one disciplinefrom the outdoor discipline list screen 170 and on doing so is presentedwith a session duration screen 171. The session duration screen 171enables the user to set the duration of the session to 30, 45, 60 or 90minutes. When the user has selected the desired session duration, aduration confirmation screen 172 is displayed for a short period.

When theuser has selected the desired session duration, a duration confirmationscreen 174 is displayed for a short period. After the display of theduration confirmation screen 174, screen 144 is displayed and thesession continues as described with reference to FIG. 11.

The calculation of points for a session or discipline by the MIDlet 35will now be described.

The points are awarded according to the Equation 2:

points=t×intensity  (2)

where t is the duration of the exercising in minutes and intensity is ameasure of a person's performance relative to a theoretical maximum. Theintensity is calculated differently depending on the way in whichperformance is entered, i.e. the choice made at screen 155 in FIG. 11.

If the performance has been entered in terms of average power, therelative performance is obtained as a percentage from Equation 3:

$\begin{matrix}{{{relative}\mspace{14mu} {performance}} = \frac{\left( {{actual}\mspace{14mu} {average}\mspace{14mu} {power}} \right) \times 100}{{theoretical}\mspace{14mu} {maximum}\mspace{14mu} {average}\mspace{14mu} {power}}} & (3)\end{matrix}$

The theoretical maximum average power is obtained according to Table 1below.

TABLE 1 Men Women Low Moderate High Low Moderate High Weight EnduranceEndurance Endurance Endurance Endurance Endurance 0-59 kg 210 W 250 W290 W 170 W 210 W 250 W 60-79 kg 250 W 275 W 330 W 210 W 230 W 290 W80-99 kg 275 W 300 W 375 W 230 W 260 W 330 W 100-300 kg 300 W 330 W 420W 260 W 290 W 375 W

Thus, a 55 kg woman having a high endurance and who had generated anaverage power of 210 W for 30 minutes would have achieved a relativeperformance of:

${84\%} = \frac{210 \times 100}{250}$

The relative performance is converted into an intensity value accordingto Table 2 below.

TABLE 2 Relative Performance Intensity  0-39% 0 40-64% 1 65-74% 2 75-84%4 85-95% 6

Thus, in the present example, the intensity is 4, giving 4×30=120points.

If the performance has been entered in terms of kilocalories, the totalenergy used in kilocalories is used to obtain an average power value.The average power value is obtained from Table 3 below using the resultof:

$\frac{kilocalories}{t}$

where t is the duration of the exercising in minutes.

TABLE 3 kcal/min Watts 1.2 20 1.8 30 2.4 40 3.0 50 3.6 60 4.2 70 4.8 805.4 90 6.0 100 6.6 110 7.2 120 7.8 130 8.4 140 9.0 150 9.6 160 10.2 17010.9 180 11.5 190 12.1 200 12.7 210 13.3 220 13.9 230 14.5 240 15.1 25015.7 260 16.3 270 16.9 280 17.5 290 18.1 300 18.7 310 19.3 320 19.9 33020.5 340 21.1 350 21.7 360 22.3 370 22.9 380 23.5 390 24.2 400 24.7 41025.3 420 25.9 430 26.5 440 27.1 450 27.7 460 28.3 470 28.9 480 29.5 49030.1 500 30.7 510

Thus, if the woman in the example above had generated 300 kilocaloriesin 30 minutes, the equivalent average power would have been 170 W (10.2kcal being the nearest value to 10 kcal in Table 3).

170 W would give a relative performance of:

${68\%} = \frac{170 \times 100}{250}$

from Equation 3 and, from Table 2 and Equation 2, 60 points.

If the performance has been entered in terms of average heart rate (HR),the points are based on the relative resistance (RR) obtained from theKarvonen formula:

$\begin{matrix}{{RR} = {\frac{{{average}\mspace{14mu} {work}\mspace{14mu} {HR}} - {{rest}\mspace{14mu} {HR}}}{{\max \mspace{14mu} {HR}} - {{rest}\mspace{14mu} {HR}}} \times 100}} & (4)\end{matrix}$

Thus, for a person having a resting heart rate of 50 bpm and a maximumheart rate of 181 bpm, an average work heart rate during exercise of 140bpm would give a relative performance of 69%. The intensity can then beobtained in accordance with Table 4 below.

TABLE 4 Relative Performance Intensity  0-50% 0 50-64% 1 65-74% 2 75-84%4 85-95% 6

In this example, the intensity is 2, giving 60 points for 30 minutes ofexercise.

If the performance has been entered using the How was it? options, theintensity is obtained from a direct mapping from the selected option tointensity as set out in Table 5 below.

TABLE 5 How was it? Intensity Easy 1 Moderate 2 Hard 4 Very Hard 6

The MIDlet 35 includes code to achieve the same result as thecalculations described above for calculating points.

Referring back to FIG. 10, if the user selects the Planner option, theMIDlet 35 enters a process 134 for guiding the user through the creationof an exercise program appropriate for the user.

Referring to FIG. 15, when the user selects the Planner option, the useris presented with a program type list screen 174 from which the user canselect weight control, endurance, strength and fitness programs. Theweight control and fitness programs combine endurance and strengthdisciplines in different ratios.

The weight control option is not displayed to high endurance users andcannot therefore be selected by them.

If the user selections the Endurance option, the user is presented witha discipline selection list screen 175 is displayed so that the user canselect the discipline that they wish to perform during their newprogram. In the present example, the options available are Cycling,Running, Rowing, Stepping and Swimming.

If the user selects Cycling, a cycling objective list screen 176 isdisplayed. The user can choose between Wellbeing and Roadrace as theirobjective. Roadrace is a more ambitious objective than Wellbeing.

If the user selects Running, a running objective list screen 177 isdisplayed. The running objective list screen 177 enables the user tochoose between, at most, Wellbeing, 10 km and Marathon.

If the user selects Rowing, a rowing objective list screen 178 isdisplayed. The rowing objective list screen 178 enables the user tochoose between Wellbeing and 6 km.

If the user selects Stepping, a running objective list screen 179 isdisplayed. The stepping objective list screen 179 enables the user tochoose between Wellbeing and Eiffel tower.

If the user selects Swimming, a running objective list screen 180 isdisplayed. The swimming objective list screen 180 enables the user tochoose between Wellbeing and 1000 m.

When the user has selected their objective, a weekday multiselect listscreen 181. The user can select the days on which the user wishes toexercise. There are limitations on the number of days that can beselected. A user who has low endurance cannot select six or seven days.Additionally, if the objective is a marathon, at least three days mustbe selected.

When the user has selected a valid set of days, a selected daysconfirmation screen 182 is displayed for a short period.

Next, the user is presented with a weeks entry screen 183 which enablesthe user to enter the number of weeks that the program is to run for.The entered number of weeks must be in the range 5 to 50. There arelimitations on the minimum number of weeks which are set out in Table 6below.

TABLE 6 Discipline Objective Low End. Mod. End. High End. RunningWellbeing 5 5 5 10 km 10 5 5 Marathon 20 15 10 Cycling Wellbeing 5 5 5Roadrace 20 15 10 Rowing Wellbeing 5 5 5 6 km 10 5 5 Swimming Wellbeing5 5 5 1000 m 10 5 5 Stepping Wellbeing 5 5 5 Eiffel tower 10 5 5

The entered number of weeks is confirmed in a weeks confirmation screen184 which is displayed for a short period.

After the number of weeks has been confirmed, the MIDlet 35 generatesthe exercise program and stores it in its record store and then displaysplanning complete screen 185 for a short period.

Referring to FIG. 16, the exercise program generation starts with thedetermination of the distributions of sessions of different intensities(step s21).

The exercise sessions are classified in increasing intensity into fourclasses a, b, c and d. The distribution of the four classes among thesessions is obtained in accordance with Table 7 below, in dependence onthe selected objective option, the number exercise sessions per week andthe endurance of the user. The Wellbeing objectives are Grade 1objectives. The 10 km, 6 km, 1000 m and Eiffel tower objectives areGrade 2 objectives and the Roadrace and Marathon objectives are Grade 3objectives.

By way of example, if a moderate endurance user chooses Wellbeing andfour sessions per week, the program would contain 25% class a sessions,30% class b session, 25% class c sessions and 20% class d sessions.

Once the session class distribution has been determined, it is necessaryto create a varied distribution of activities, meeting the determinedclass distribution criterion, across all but the last week of theprogram (step s22). Thus, if, for example, the user has specified a 15week program, the activity distribution process distributes activitiesacross, in this example, 4 sessions in each of 14 weeks, giving a totalof 56 sessions. Of these sessions, 14 will be class a sessions, 17 willbe class b sessions, 14 will be class c sessions and 11 will be class dsessions. The numbers of sessions of each class are rounded asnecessary.

The activities are allocated to sessions in the order class d to classa. A class d step value is initially obtained by integer dividing thenumber of sessions by the number of class a sessions, i.e. 56 div 11=5in the present example. Class d activities are therefore allocated tosessions 5, 10, 15, 20. 25, 30, 35, 40, 45, 50 and 55. The actualactivities are chosen at random from the class d entries, i.e.activities d1, . . . , d8, in Table 8 below. The process is thenrepeated for class c sessions. In the present example, the class c stepvalue is 56 div 14=4. The class c sessions would therefore be 4, 8, 12,16, 21 (session 20 is already occupied by a class d activity), 24, 28,32, 36, 41 (session 40 is already occupied by a class d activity), 44,48, 52 and 56. For the class b sessions, the step value is 56 div 17=3and the class b sessions are 3, 6, 9, 13 (session 12 is already occupiedby a class c activity), 17 (session 15 is already occupied by a class dactivity and session 16 is already occupied by a class c activity), 18,22 (session 21 is already occupied by a class c activity), 26 (session24 is already occupied by a class c activity and session 25 is alreadyoccupied by a class d activity), 27, 31 (session 30 is already occupiedby a class d activity), 33, 37 (session 36 is already occupied by aclass c activity), 39, 42, 46 (session 45 is already occupied by a classd activity), 49 (session 48 is already occupied by a class c activity)and 51. Finally, the remaining sessions are made class a sessions. Thefinal session pattern is shown in FIG. 17.

When the sessions of all but the last week have been allocatedactivities, activities are allocated to the sessions of the final weekof the program (step s23). The session classes for the final week areallocated according to Table 9 with the activities selected randomlyfrom Table 8 according to session class.

TABLE 9 Sessions per week set by user Monday Thursday Friday 2 a 3 a 4 aa 5 a a 6 a d a 7 a d a

Thus, in the example given above, the final week consists of two class asessions on the Thursday and the Friday (see FIG. 17).

The completed program is stored in the MIDlet's record store.

Referring to FIG. 18, if the user selections the Strength option fromthe program type list screen 174, the user is presented with an exercisetype screen 186 giving the user the opportunity of selecting eitherSculpturing or Functional training. However, Functional training is notavailable to users having low strength. After selecting the exercisetype, the user is presented with a weekday multiselect list screen 187.The user can select the days on which the user wishes to exercise. Whenthe user has selected a valid set of days, a selected days confirmationscreen 188 is displayed for a short period.

The user is then presented with a session length list screen 189 fromwhich the user can select 30, 45, 60 or 90 minutes as the length foreach sessions. The session length selected by the user is confirmed by asession length confirmation screen 190 which displayed for a shortperiod.

If the user has selected Sculpturing from the exercise type screen 186,the user is now presented with an equipment selection list screen 191which enables to user to specify the equipment, if any, that the userwishes to use. Once the equipment has been specified by the user,

Next, the user is presented with a weeks entry screen 192 which enablesthe user to enter the number of weeks that the program is to last for.The entered number of weeks must be in the range 5 to 50. The enterednumber of weeks is confirmed in a weeks confirmation screen 193 which isdisplayed for a short period.

If the user has selected Functional training from the exercise typescreen 186, the session length confirmation screen 190 is followeddirectly by the weeks entry screen 192. Functional training always makesuse of free weights.

After the number of weeks that the program is to be last has beenentered, the MIDlet 35 generates the exercise program and then displaysplanning complete screen 194 for a short period.

Referring to FIG. 19, the first step of generating a strength exerciseprogram is to select the program category (step s31) on the basis of theuser's strength level, the selected number of sessions per week and thespecified session length in accordance with Table 10 below.

TABLE 10 Sculpturing (s) Sessions per Session Length (mins) StrengthWeek 30 45 60 90 Low 2 1 2  3  4 3 1 2 3, 7, 11 8.12 Moderate 2 1 2  3 4 3 1 2 3, 7, 11 8.12 4 5, 9 6 7, 11 — High 2 1 2  3  4 3 1 2 3, 7, 118, 12 4 5, 9 6 7, 11 8, 12 5 20  21 22 — 6 20  21 22 — Functional (f)High 2 1 13 14 15 3 1 13 14 15 4 16  17 18 19

By way of example, if a moderately strong user selects three one-hoursessions per week of sculpturing, the program category is selected atrandom from categories 3, 7 and 11. In many cases, there is only oneprogram category available and in these cases the available categorymust be selected.

Once the program category has been obtained, the exercise combinationsavailable for the selected category are obtained in accordance withTable 11 below (step s32).

In the present example, the category needed to be selected fromcategories 3, 7 and 11. I will be assumed that category 7 was selectedby a random selection process. Table 11 includes two category 7 exercisecombinations, categories 7.1 and 7.2.

The available exercise combinations are allocated to cyclically to thesessions of the program (step s33). Thus, if there is only one exercisecombination, this combination will be used for all sessions. If thereare two exercise combinations, the sessions will alternate between themand if there are more than two exercise combinations, these will berepeated in sessions a recurring sequence.

Each component of an exercise combination differ depending on whetherthe user has selected machine, free weight or a combination of machineand free weight exercises and may have a plurality of variants withinthese groups. The available variants are set out in Table 12 below.

An array having a column for each session and a row for each exercise inthe selected exercise category is now populated with exercise variants(step s34). An initial variant of each exercise of each category isselected. Where the sets of variants of different exercises overlap, thechosen variants must be different. These selected variants are thenadded to the array in the elements for the appropriate sessions andexercises. If there are 10 or less week's worth of sessions, theseexercises are used throughout the program.

If the program is to last for more than ten weeks, three of the exercisevariants are replaced with unused variants for the 11^(th) andsucceeding weeks. Thereafter, if the program is sufficiently long,further groups of three exercise variants are replaced every five weeks.Only exercise variants in the original selection can be replaced untilall of the originally selected exercise variants have been replaced. Thereplacing variants may not duplicate an exercise variant already in thearray.

When the array has been populated, it is saved to the MIDlet's recordstore and the MIDlet 35 displays a planning complete screen 195 for ashort period.

Referring to FIG. 20, if the user selects the Weight control option fromthe program type list screen 174, the user is presented with anequipment selection list screen 196 which enables to user to specify theequipment, if any, that the user wishes to use.

After the user has made their equipment selection, a disciplineselection list screen 197 is displayed so that the user can select thediscipline that they wish to perform during their new program. In thepresent example, the options available are Cycling, Running, Rowing,Stepping and Swimming.

After the user has selected a discipline from the discipline selectionlist screen 197, the MIDlet 35 then displays a weekday multiselect listscreen 198 which enables a user to identify the days of each week onwhich they are to exercise. Only 2 to 4 days may be selected forexercising in each week by a low endurance user and only 2 to 5 days byother users. The number of days selected is then displayed in a daysconfirmation screen 199 which is displayed for a short period.

A session time list screen 200 is then displayed to enable the user toselect an exercise session length from among 30, 45, 60 and 90 minutes.Low endurance users cannot select 90-minutes for the session length. Theselected exercise session length is confirmed by a session lengthconfirmation screen 201 which is displayed for a short period.

Next, the user is presented with a weeks entry screen 202 which enablesthe user to enter the number of weeks that the program is to run for.The entered number of weeks must be in the range 5 to 50. The enterednumber of weeks is confirmed in a weeks confirmation screen 201 which isdisplayed for a short period.

When the number of weeks has been confirmed, the MIDlet 35 generates theweight control exercise program for the user.

Referring to FIG. 21, the MIDlet 35 first determines a mode for theprogram in dependence on the number of sessions per week and the sessionlength entered by the user and the user's endurance level with referenceto the data in Tables 13 and 14 below.

TABLE 14 Session Length Endurance Sessions 0.5 0.45 1 1.5 LOW 2 1 5 9 31 5 9 4 1 6 10 MODERATE 2 1 5 9 12 3 1 5 9 12 4 1 6 10 13 5 3 7 10 13

TABLE 15 Mode Exercise Mix 1 30 min aerobic exercise 3 2 × 30 minstrength + 3 × 30 min aerobic exercise 5 45 min aerobic exercise 6 2 ×(45 min aerobic exercise + 45 min strength switching) 7 2 × 45 minstrength + 3 × 45 min aerobic exercise switching 9 30 min aerobicexercise + 30 min strength 10 30 min aerobic exercise + 30 min strengthsplit 12 60 min aerobic exercise + 30 min strength 13 45 min aerobicexercise + 45 min strength split

The mode number is obtained from Table 14 and the aerobic/strengthexercise mix is obtained from Table 15. Aerobic, i.e. endurance,exercising and strength exercising are allocated to sessions inaccordance with Table 15. For instance, if mode 1 is used, all sessionsare aerobic. However, if mode 6 is used, 45 minute sessions alternatebetween aerobic and strength exercises.

The aerobic sessions are allocated disciplines in accordance with theGrade 1 (Wellbeing) section of Table 7 and Table 8 above (step s43).

Considering now, by way of example, a person who has moderate enduranceand has selected four sessions per week over 10 weeks, cycling andmachines, Table 14 give use exercise mode 6 and Table 15 indicates thatthis comprises alternating sessions of aerobic and strength exercise.Thus, there are 20 sessions that need to be filled with 7 (33%) class asessions, 6 (32%) class b sessions, 4 (20%) class c sessions and 3 (15%)class d sessions.

The sessions are allocated classes by the algorithm described above withreference all but the last week of an endurance program. Thus, in thepresent example, the sessions are allocated classes as shown in FIG. 22.

If the mode includes strength sessions (step s44), sculpturing exercisesare allocated to the strength sessions in accordance with Tables 9 and10 and the allocation algorithm described above with reference togeneration of a strength exercise program.

In the case of the present example, exercise category 6 would beobtained from Table 10. Assuming that exercise combination 6.1 wasselected at random from combinations 6.1 and 6.2, each strength sessionwill need to include exercises chest 1, back 1, shoulders 1, triceps 1,biceps 1, chest 2 and back 2 as defined in Table 11. Consequently, thestrength sessions (the even sessions in FIG. 22), may comprise: chestpresses, pull downs, shoulder presses, one arm extensions, preachercurls, cable crosses and seated rowing.

The completed program is saved in the MIDlet's record store.

If the user selects the Fitness option from the program type list screen174, the user progresses through the same sequence of screens as whenWeight control is selected. The only difference in the screensthemselves is that the title is “Fitness” instead of “Weight control”.The generation of fitness programs is substantially the same as thegeneration of weight control programs. However, the mode is determinedin accordance with Table 16 below.

TABLE 16 Session Length Endurance Sessions 0.5 0.45 1 1.5 LOW 2 1 5 9 31 5 9 4 2 6 10 MODERATE 2 1 5 9 12 3 1 5 9 12 4 1 6 10 13 5 3 7 10 —HIGH 2 1 5 9 12 3 1 6 9 12 4 2 6 10 13 5 3 7 10 — 6 4 8 11 —

Table 16 also indicates the session number and duration combinationsthat are allowed for users having different endurances.

The mode definitions for fitness programs are set out in Table 17 below.

TABLE 17 Mode Exercise Mix 1 30 min aerobic training 2 30 min aerobictraining and 30 min strength (switching) 3 2 × 30 min strength + 3 × 30min aerobic training 4 3 × 30 min strength + 3 × 30 min aerobic training5 45 min aerobic training 6 45 min aerobic training + 45 min strengthswitching 7 3 × 45 min strength + 2 × 45 min aerobic training switching8 3 × 45 min strength + 3 × 45 min aerobic training switching 9 30 minaerobic training + 30 min strength 10 30 min aerobic training + 30 minstrength split 11 3 × 60 min strength + 3 × 60 min aerobic training 1245 min aerobic training + 45 min strength 13 45 min aerobic training +45 min strength split

The process of allocating exercises to sessions for a fitness program isthe same as that described above for a weight control process.

The completed program is saved to the MIDlet's record store.

If the user selects the Start Planned option from the main screen 132,the MIDlet 35 performs a process 135 to guide the user through anexercise session of the current plan.

Referring to FIG. 23, when the Start Planned option has been selected,it is determined whether there is a pending exercise session for thecurrent day. If there is not a pending session, the user is informed ofthis by a no session information screen 206, which is displayed for ashort period before the display returns to the main screen 132.

If, however, there is a pending session, the user is presented with asession options list screen 207. The user can choose to start thepending session, delete the pending session or delete the entire programfrom the session options list screen 207.

If the user chooses to start the pending session, it is determinedwhether the session comprises a plurality of exercises. If the sessionconsists of only one exercise, the parameters of the session aredetermined. The activity is obtained from the stored data defining thecurrent plan. The default activity length is obtained from the Table 8information and multiplied by factor representing the user's endurancelevel/1000. The factor is initially 1 for a low endurance person, 1.4for a moderate endurance person and 1.7 for a high endurance person. Aswill be explained below, the user's endurance may be modified as theuser progresses through a program. The pattern of intervals and pauses,if any is also obtained from the Table 8 information. Enough informationis now available for the user to be guided through the session.

When the activity information has been obtained, the user is presentedwith an information screen 208, reminding the user to warm up beforeexercising, which then gives way to an exercise guidance screen 209. Theexercise guidance screen 209 is generally arranged as shown in FIG. 12but contains information relevant to the current session.

When the user selects the Start command from the exercise guidancescreen 209, the MIDlet 35 begins timing the user's performance of thecurrent session's activity. During this period, the MIDlet 35occasionally displays motivational messages in motivational messagescreens 210. For instance, a motivational message may inform a user of afoodstuff that has a calorific value corresponding to the amount ofenergy notionally produced by the user while performing the discipline.The motivational message screens 210 are displayed for a short periodbefore the display reverts to the exercise guidance screen 209. TheMIDlet 35 also generates audio signals and updates the exercise guidancescreen 209 to inform the user when to pause or vary their activity inthe cases of interval and fartlek exercises.

If the user selects Options from the exercise guidance screen 209, theuser is presented with an options menu 211 comprising End discipline andExit session options. If the user selects the End discipline option, theuser is presented with an end discipline confirmation screen 212 and, ifthe user confirms that the discipline is to be ended, the MIDlet 35stops timing and displays session options list screen 207 again. Thediscipline is not recorded as having been completed.

If the user selects the Exit session option, the user is presented withan exit session confirmation screen 213 and, if the user confirms thatthe discipline is to be ended, the MIDlet 35 stops timing and displaysthe main screen 132 again.

If the user selects the Pause command from the exercise guidance screen209, the user is presented with a paused discipline screen 215. TheMIDlet's timing of the discipline is paused while the paused disciplinescreen 215 is being displayed. When the user selects the Continuecommand from the paused discipline screen 215, the MIDlet 35 restartsits timing operation and displays the exercise guidance screen 209again. The user can also end the current discipline or exit the currentsession by selecting the Options from the paused discipline screen 215which takes the user to the options menu screen 211.

When the period calculated for the current discipline has elapsed,allowing for any pauses, the MIDlet 35 displays a discipline completedscreen 216, which advises the user to warm down, for a short period. TheMIDlet 35 also produces an audible indication that the set period haselapsed. The discipline completed screen 216 is replaced with aregistration list screen 217 is displayed.

From the user's perspective the registration process 218 is as describedabove in the context of the fast start process 133. It differs in thatthe MIDlet 35 adds the points gained to a local record of the user'sprocess through the program.

If it is determined that the current session comprises a plurality ifdisciplines, the user is presented with a discipline list screen 219which consists of the disciplines that the user must perform in thecurrent session. The user can now select the first discipline to beperformed. In the present example, the disciplines are Bench press, Pullover and Cable cross and the user has selected Bench press. Icons besidethe elements in the discipline list screen 219 indicate whether thedisciplines have been not been started, have been completed or have beeninterrupted.

On selecting the starting discipline, the user is presented for a shortperiod with an information screen 220 which reminds the user to warm upbefore exercising. The information screen 220 is replaced by a exerciseguidance screen 221.

Referring to FIG. 24, the exercise guidance screen 221 comprises a title2001, an exercise themed graphic 2002, an discipline progress section2003 and a scrolling instruction section 2004. The title 2001 states thediscipline. The discipline progress section 2003 comprises two sections2003 a, 2003 b which display the progress through the current disciplinein terms of sets and the number of reps in current set respectively Theinstruction section 2004 provides additional guidance and explanation tothe user.

Referring back to FIG. 23, the details of the selected discipline areobtained from Table 18 below which defines the patterns of reps formingsets as a function of progress through a program and program type, i.e.sculpturing or functional training.

TABLE 18 Weeks 1-5 6-10 11-15 16-20 21-25 26-30 31- Sculpturing (s) 3sets 3 × 12 3 × 10 3 × 8 12, 6, 12 6, 9, 12 12, 9, 6 12, 8, 12 4 sets 4× 12 4 × 10 4 × 8 12, 6, 6, 12 6, 8, 10, 12 8, 8, 12, 12 12, 8, 8, 12Functional (f) 3 sets 3 × 6  3 × 5  3 × 4 3 × 3 6, 3, 6 6, 4, 2 5, 2, 54 sets 4 × 6  4 × 5  4 × 4 4 × 3 6, 3, 3, 6 2, 4, 6, 6 4, 2, 2, 6 Abs,lower back 3 sets 3 × 20 all weeks 4 sets 4 × 20

When the user selects the start option from the exercise guidance screen221, the main command changes from Start to Next and the informationsection 1004 displays the maximum weight lifted from the precedingsession. When the user has completed the first set of reps, the userselects the Next command and the exercise guidance screen 221 is updatedto indicate the current set and the number of reps in the current set.The user keeps performing the sets of reps and selecting the Nextcommand until all of the sets have been completed. When all of the setshave been completed, the exercise guidance screen 221 is updated so thatthe Next command is replaced with a Done command. When the user selectsthe Done command, a maximum weight entry screen 222 which enables theuser to enter the maximum weight lifted in the current session so thatit can be recorded. The entered weight is confirmed in a weightconfirmation screen 223 is displayed for a short period. Then, if thereare still disciplines to perform, the discipline list screen 219 isdisplayed again. Otherwise, the registration process is joined at screen164, which in this case does not refer to points but provides a summaryof the weights lifted.

If the user selects the Delete session option from the session optionslist screen 207, a delete session screen 224 is displayed. If the userconfirms that the current session should be deleted, the current sessionis marked as completed without any record of performance, i.e. points orweights, and a delete session confirmation screen 225 is displayed for ashort period before the display reverts to the main screen 132.

If the user selects the Delete whole plan option from the sessionoptions list screen 207, a delete whole plan screen 224 is displayed. Ifthe user confirms that the current plan should be deleted, the datadefining the current plan is erased and a delete whole plan confirmationscreen 225 is displayed for a short period before the display reverts tothe main screen 132.

As a programs having an endurance element progress, the user'sperformance is monitored by reference to the accumulated points. Moreparticularly, after every five weeks, the user's endurance level isadjusted.

Referring to FIG. 25, in order to adjust the user's endurance level, itis determined whether the number of sessions per week in the currentplan is 2, 3, 4 or one of 5, 6 or 7 (step s51). Two variables, K1 andK2, are then set in dependence on the number of sessions per week (stepss52 to s55). It is the determined whether the user has made progress bycomparing the accumulated points in the preceding five weeks with atarget value, equivalent to 60% the theoretical maximum performancecalculated from the user's personal data and additional data (step s56).If progress is being made, the user's endurance level is increasedaccording to the formula:

${{new}\mspace{14mu} {endurance}\mspace{14mu} {level}} = {{{old}\mspace{14mu} {endurance}\mspace{14mu} {level}} + \frac{\left( {{K\; 1} - {K\; 2 \times {old}\mspace{14mu} {endurance}\mspace{14mu} {level}}} \right)}{1000}}$

However, if the user is performing poorly, their endurance level isreduced according to the formula:

${{new}\mspace{14mu} {endurance}\mspace{14mu} {level}} = {{{old}\mspace{14mu} {endurance}\mspace{14mu} {level}} + \frac{\left( {475 + {1000 \times {old}\mspace{14mu} {endurance}\mspace{14mu} {level}} - {K\; 1}} \right)}{1000 - {K\; 2}}}$

The new endurance level is then used for setting the periods for whichdisciplines must be performed.

If the user's performance is substantially at odds with the expectedperformance, a screen may be displayed suggesting that the usersendurance in the user's personal data be changed up or down asnecessary.

If the user selects the Diary option from the main screen 132, a diaryprocess 136 is performed.

Referring to FIG. 26, selecting the Diary option from the main screen132 causes a calendar screen 228 to be displayed. The calendar screen228 has an option menu comprising View and Update options. Selecting theView option causes a detail screen 229 to be displayed. The detailscreen 229 includes detail of any sessions on the day currently selectedin the calendar screen 228 and other date-specific information.Selecting the Update option causes the mobile phone 2 to request updateinformation from the server 3. The update information may compriseinformation about forthcoming events that may be of interest to theuser.

If the user selects the Information option, the user is provided withinformation about the MIDlet 35 and more generally about exercise andfitness.

Referring to FIG. 27, if the user selects the Synchronization option,the user is presented with a synchronization screen 230. The user canopt to transfer data to a personal computer using a cable or infraredlink (not shown). The user can also opt to transmit data to the server 3via the Internet 5. On the first occasion that the Internet option isselected, the MIDlet 35 causes the mobile phone 2 to send 231 aregistration SMS message to the server 3. The user then receives a replySMS message in the normal manner. The reply message includes a usernameand password for accessing the server 3. On subsequent occasions,selecting the Internet option results in data being transmitted 232 tothe server 3.

The data transmitted in the synchronization process 138 is an XMLdocument comprising a definition of the current program and a record ofthe user progress with the current program.

Referring to FIG. 28, the second exemplary system comprises an activitymonitor 1, a mobile phone 2 and a server 3. The activity monitor 1 canmonitor the movement of a user and derive a value for the energyexpended by the user while performing the monitored movement. The mobilephone 2 and the activity monitor 1 can communicate with each other usinginfrared signalling. Other wireless techniques, e.g. WiFi and Bluetooth,or wired techniques may be used instead of infrared signalling.

The mobile phone 2 can communicate with the server 3 via a mobile phonenetwork 4 and the Internet 5 using xml messages and the HTTP protocol.The mobile phone 2 supports J2ME (Java 2 Micro Edition) MIDlets and thefitness program functions of the mobile phone 2 are implemented by aMIDlet.

The activity monitor 1 can be conveniently worn on the person duringexercise.

The display 13 is connected to output pins ofthe microcontroller 11 and is controlled by the microcontroller 11 todisplay information relating to a current activity and to providefeedback to the user when the user is setting up the activity monitor 1.

The infrared transceiver 15 is coupled to a serial port of themicrocontroller 11 for bidirectional communication with the mobile phone2.

The microcontroller 11 is responsive to pressing of the buttons 14 forthe input of user data, comprising the user's name, date of birth,height, weight and sex. This information enables the monitor tocalculate the energy expended by the user during a sensed activity, forstarting and stopping sensing and for communication with the mobilephone 2.

The MIDlet 35 of the second embodiment differs from that of the firstembodiment in that the registration process can accept energy expendedper minute data wirelessly from the activity monitor in addition to themanual methods described above. Points are derived from the wirelesslyreceived data in accordance with Equation 2 and Tables 2 and 3 above.

Referring to FIG. 30, during registration, the registration list screen155 includes an additional Wireless option. If the user selects theWireless option, the mobile phone 2 is put into a state in which it canreceive performance data from the activity monitor 2. Duringcommunication, the MIDlet 35 31 displays a communication informationscreen 250.

The energy expended is transmitted from the activity monitor 1 to themobile phone 2 in a data package.

Referring to FIG. 31, the data package 300 comprises a package header301 and a package body 302. The package header 301 comprises version303, package length 304, time 305, final flag 306 and command 307fields. The version field 303 is 1 byte and can be a value from 0 to255.
